Visible crew/equipment: When Claire runs away from Bob after he calls her "Ms. Bennet", you can see Bob's shadow and another person's shadow on the ground. Since no one else was standing next to them, it has to be a crew member, most likely a camera man based on the odd shape of the shadow.
Trivia: There are a number of other Star Trek references in Heroes. In episode 15 (Run!), Hope refers to Hiro as "Sulu." George Takei, who played the original Sulu plays Hiro's father. And at one point (and several other times throughout the show) Hiro gives the Vulcan hand symbol that Spock always used when he would say "live long and prosper." Zachary Quinto, who plays Sylar, would also later play Spock in the 2009 reboot Star Trek.
